my suspicion (and it is only that at this juncture) is that the buyers may be trying to purchase some "cover" for themselves as they -- and/or their affiliates -- were behind the ridiculous manipulation that saw this stock rocket to $6.74 on no new news.
and, of course, there's no guarantee that they will actually close on the PP as scheduled; if that were to happen, it would send the stock reeling badly. if the motives are nefarious, they -- and/or their affiliates -- could be heavily short right now
I'll withhold further judgment until I get a chance to read the actual PP filings (they are not yet available on sec.gov) -- and I could very well be wrong about all of this -- but none of it sits well with me. I'm staying out until the dust clears
